I To all whom it may concern:

Be it known that I, CARL GABRIELSON, a

. citizen of the United States, and residentof Syracuse, Onondagacounty,'State of New ork, have invented certain new and usefulImprovements in TypeWVriting Machines, of which the following is aspecification.

This application is a division of my application Serial Number 205,718filed April 30, 1904.

' The invention mounting of the machine and the ing devices.

he invention will be particularly 'described in connection with theaccompanying drawing, in which,

Figure 1 is a rear view partly in section of a portion of a typewritingmachine sutficient to illustrate the present invention; Fig. 2 is aperspective View of the bell supporting bracket and the device foroperating the bell hammer; and Fig 3 is ,a partial side elevation.

Referring to the drawing, 1. indicates the top plate of the fixed frameof a typewriting machine, 2 a portion of the carriage, 3 the carriagerack, 41 the escape wheel of the carriage feed mechanism and 5 therocker which carries the escape pawls which cooperate with the wheel 4.A rock shaft 6, which is not longitudinally adjustable or movable, isrocked slightly as the carriage nears the end of its travel by deviceswhich need not be described in this specification. This rock shaftcarries an arm 7 to which is connected a. depending vertically movablerod 8 having a shoulder 9 adapted to bear upon an arm 10 of the bellhammer 11. By these means the bell hammer is raised when the shaft 6 isrocked and permitted to drop when the reverse movement of the shaft 6takes place.

The bell 12 is. mounted upon a bracket 13 which is connected to a theframe and adjustable thereon in an upand-down direction. As shown, thebracket relates particularly to the alarm bell on a typewritingadjustment of the bell ringfixed part 14 of 13 is in the form of a leverpivoted at 15 and secured in place by a screw 16 passing through theslot 17in the lever and into the fixed part 14. The bell is fixed to anarm 18 of the bracket 13, and the free end of the .bracket 19 isU-shaped, forming a yoke in is pivoted. The belt which the bell hammerhammer preferably has a U-shaped portion 20fforming aninverted yoke anda pivot 21 .passes through the yokes l9 and 20. A light spring 22 ispreferably provided to assist in the striking movement of the bellhammer, although the hammer erated by gravity if desired."

As .prcviously stated the bell hammer is raised when the shaft 6 isrocked in one direction and dropped when the shaft 6 is quickly operatedin the reverse direction. The means for operating described in theaforesaid application, Serial Number 205,718. of which this applicationis a division. By providing a support for the bell and its hammer whichis adjustable with relation to the hammer operating device, the strokeof the bell" hammer can be adjusted quickly and satisfactorily withoutdisconnecting 0r disarranging any of the bell ringing mechanism.

It will be evident that various changes in details of construction maybe adopted without. departing from the the present invention.

Without limiting myself to the construction and arrangement illustratedand described, I claim,

1.. In a typewriting machine, tion with a fixed frame and a horizontallyarranged rock-shaft, of a bell support car.- ried by said frame, av belland bell hammer carried by said support. and a connection of saidrock-shaft arranged to operate the bell hammer when the shaft is rocked,said bell support being adjustable toward and away from said rock-shaftand connection where by the stroke of the hammer may be readilyadjusted.

2. In a typewriting machine. the combination with the fixed frame, otalever pivoted may be opthe shaft are fully I precise the coinbinaspiritand scope of to said frame at oneend and provided with In testimonywhereof I a fiix my signature aslot intermediate its ends, a clamping inpresence of two Witnesses.

screw passing through said slot into said' I I frame, a bell mounted onsaid lever, a bell ,CARL GABRIELSON' 5 hammer pivotally connected to thefree end Witnesses:

of said lever, and a part cotiperating with C. M. STEVENS,

said bell hammer to ring the bell. I 0. F. PARS
